Yes, Smith has posted an impressive record during his tenure in Atlanta. However, this isn't the first time his team has blown 2nd half/4th quarter double digit leads, as we've seen in this year's playoffs.

Yeah, coming into the Niners game, he was undefeated going into the 4th quarter with leads, but nonetheless numerous times his team was able to dodge bullets after giving up leads late in games. But this time around it has finally nipped them in the bud.

FYI, this was pretty much why Wade Phillips was ran out of Dallas(for doing the same thing - allowing his team to lay off the gas pedal when grabbing double digit leads). From what I've seen, Smith is Phillips v. 2.0.
